Azure Data Explorer vs Tenzir

Azure Data Explorer and Tenzir are both enterprise data pipeline solutions. Azure Data Explorer microsoft's fast data analytics service for real-time analysis of streaming security data, while Tenzir open-source security data pipeline with native support for security-specific data formats. The best choice depends on your organization's size, technical requirements, and budget.

Choose Azure Data Explorer if massive scale at lower cost than SIEM solutions is your priority and microsoft-centric organizations wanting a scalable security data lake with powerful KQL analytics at lower cost than SIEM. Choose Tenzir if fully open-source with transparent codebase matters most and security teams wanting an open-source, security-native data pipeline with transparent code and no vendor lock-in.

Tenzir starts at Free (open source) / Enterprise support available (open source with commercial support). Azure Data Explorer starts at Pay-as-you-go (compute + storage) / Reserved capacity discounts (consumption-based (compute + storage)). As always, the sticker price only tells part of the story. Factor in add-ons, implementation costs, and what's actually included at each tier.

It depends on how deeply Azure Data Explorer is embedded in your stack. Most teams run both in parallel for a few weeks before cutting over. Check whether Tenzir supports importing your existing configs or policies. That's usually the biggest time sink.
